TILE as well according to this list: https://help.mikrotik.com/docs/spaces/ROS/pages/197984280/Back+To+Home
I’m not sure though the reasoning behind it, since any device supporting WireGuard and RouterOS v7 should be capable of using it. The only Mikrotiik devices I’ve dealt with were ARM/ARM64 and PowerPC (RB1100AHx2). The RB1100AHx2 was not upgradable to ROS 7 directly (the upgrade had to be performed using NetInstall) because ROS 7 only supports those architectures officially.
However, I wonder if now that ROS7 lts was released, it’s officially supported in all architectures, hence bringing BTH support.
The best way to test though would be by upgrading any of those devices to latest ROS 7 and checking if BTH exists on IP/Cloud.
Beside, can’t you use RoMON over EoIP or any L2 tunnel as well?
